Amino acids in our body are mostly found in the “L-form” because of the way life has evolved. The “L” and “D” forms are like mirror images of each other, just like how our left and right hands are mirror images. The “L-form” was chosen by nature during the early stages of life on Earth, and all living things, including humans, have followed this pattern.
The enzymes in our body, which are proteins that help chemical reactions happen, are designed to work with L-amino acids. If the amino acids were in the D-form, the enzymes wouldn’t recognize them properly, and the body wouldn’t be able to use them as building blocks for proteins or for other important functions.
The preference for L-amino acids is crucial for life because it ensures consistency in the structure and function of proteins. If both L- and D-forms were used, it could lead to errors in protein formation, which might result in non-functional or harmful proteins. So, the L-form has become the standard for amino acids in all living organisms, including humans.
